Final answer:
The law of supply states that there is a direct relationship between price and quantity supplied, with all other factors being constant. Therefore, the answer to whether they are related is 'directly related, ceteris paribus.'
Step-by-step explanation:
The law of supply is an economic principle asserting a direct relationship between the price of a good or service and the quantity of that good or service that producers are willing to supply. According to this principle, if all other factors remain constant (ceteris paribus), an increase in price results in an increase in the quantity supplied, whereas a decrease in price leads to a decrease in the quantity supplied.
The correct answer to the student's question is 'directly related, ceteris paribus.' This means that the relationship between price and quantity supplied is direct, such that as the price increases, so does the quantity supplied, and vice versa, when all other factors are held constant.
